Questions and Answers

1.

What type of material is this tool typically used to cut?
- A.
  
  Plastic
- B.
  
  Wood
- C.
  
  Glass
- D.
  
  Metal
Correct Answer
D. Metal

Explanation
This tool is typically used to cut metal because it is strong and durable enough to handle the hardness and toughness of metal materials. It is not commonly used to cut plastic, wood, or glass as these materials can be cut with other types of tools that are better suited for their properties.

The ground wire is which color?
- A.
  
  White
- B.
  
  Blue
- C.
  
  Black
- D.
  
  Green
Correct Answer
D. Green

Explanation
The ground wire is typically green in color. This wire is used in electrical systems to provide a safe path for electrical currents to flow into the ground in case of a fault or short circuit. By connecting the ground wire to the earth, it helps to prevent electric shocks and protect both people and electrical devices from potential harm.

Before working on an electrical subpanel, you should always:
- A.
  
  Wear safety glasses
- B.
  
  Turn off power
- C.
  
  Install a circuit "lock out" tag
- D.
  
  All of the above
Correct Answer
D. All of the above

Explanation
Before working on an electrical subpanel, it is important to take necessary safety precautions. Wearing safety glasses protects the eyes from potential hazards such as flying debris or sparks. Turning off the power ensures that there is no electrical current flowing through the panel, reducing the risk of electric shock. Installing a circuit "lock out" tag prevents others from accidentally turning the power back on while work is being done, providing an additional layer of safety. Therefore, all of the above options should be followed before working on an electrical subpanel.

Choose the smallest wire:
- A.
  
  #2 gauge
- B.
  
  #6 gauge
- C.
  
  #12 gauge
- D.
  
  #14 gauge
Correct Answer
D. #14 gauge

Explanation
The #14 gauge wire is the smallest wire among the given options. Wire gauge refers to the thickness or diameter of the wire. In the American Wire Gauge (AWG) system, a smaller gauge number indicates a thicker wire. Therefore, the #14 gauge wire is the smallest wire in this context.

What is the best way to clean up latex paint?
- A.
  
  Soap and Warm Water
- B.
  
  Gasoline
- C.
  
  Paint Thinner
- D.
  
  Acetone
Correct Answer
A. Soap and Warm Water

Explanation
Soap and warm water is the best way to clean up latex paint because latex paint is water-based. Soap helps to break down the paint particles, while warm water helps to loosen and dissolve the paint. This method is safe and effective for cleaning brushes, rollers, and other painting tools. Gasoline, paint thinner, and acetone are not recommended for cleaning up latex paint as they are flammable and can damage the paint brushes and tools.

A thermocouple is used to:
- A.
  
  Hold a pilot light open
- B.
  
  Clean water
- C.
  
  Test water
- D.
  
  Start a BBQ
Correct Answer
A. Hold a pilot light open

Explanation
A thermocouple is a device that is used to hold a pilot light open. It is a safety mechanism commonly found in gas-powered appliances such as water heaters and furnaces. The thermocouple senses the presence of a flame from the pilot light and generates a small electrical current to keep the gas valve open. If the pilot light goes out, the thermocouple stops producing the current, causing the gas valve to close and preventing any gas from leaking into the appliance.

How many yards of carpet are needed for a room measuring 9' X 12'?
- A.
  
  24
- B.
  
  36
- C.
  
  108
- D.
  
  56
Correct Answer
B. 36

Explanation
To calculate the number of yards of carpet needed for a room measuring 9' x 12', we need to convert the measurements to yards. Since there are 3 feet in a yard, the room measures 3 yards x 4 yards. Therefore, we need 12 square yards of carpet. However, carpet is typically sold in rolls of 3 feet wide, which is equivalent to 1 yard. Therefore, we need to divide the square yardage by the width of the carpet roll, which is 3 feet or 1 yard. So, 12 square yards divided by 1 yard equals 12 yards of carpet. The correct answer is 36.

How do you clear the drain if a tub is stopped up and there is no clean out?
- A.
  
  Cut open the wall to access the vent pipe
- B.
  
  Go to the roof vent and run a snake
- C.
  
  Put the snake through the tub overflow
- D.
  
  Remove the tub
Correct Answer
C. Put the snake through the tub overflow

Explanation
To clear a stopped-up tub drain without a clean out, one can put a snake through the tub overflow. The tub overflow is a small opening located near the top of the tub, usually covered by a metal plate. By inserting a snake through this opening and maneuvering it down the drain, it can help break up and remove any clogs that may be causing the blockage. This method is a common and effective way to clear a tub drain without having to cut open walls or remove the tub itself.

What is the most common spacing for studs in a typical wall?
- A.
  
  10" on Center
- B.
  
  18" on Center
- C.
  
  16" on Center
- D.
  
  12" on Center
Correct Answer
C. 16" on Center

Explanation
The most common spacing for studs in a typical wall is 16" on center. This means that the center of each stud is placed 16 inches apart from the center of the adjacent stud. This spacing is widely used in construction because it provides adequate support and stability to the wall while also allowing for the installation of standard-sized building materials such as drywall or plywood.

Identify this piece of equipment:
- A.
  
  Capacitor: Stores electrical energy
- B.
  
  Oven Thermostat: Gas and electric stoves
- C.
  
  Key gauge: Measures and cuts in keys that correspond to pin numbers
- D.
  
  Range hood filter: stove range hoods
Correct Answer
C. Key gauge: Measures and cuts in keys that correspond to pin numbers

Explanation
The key gauge is a piece of equipment used to measure and cut keys that correspond to pin numbers. This means that it is a tool specifically designed for locksmiths or individuals who need to create keys that match specific lock mechanisms. The key gauge allows for precise measurements and cuts to ensure that the key fits perfectly and can unlock the corresponding lock.
